/ Replacing Pod Mat Foam

I have a Pod hinged mat (the ones around 1M sq when opened up). The cover is absolutely fine, but the foam was getting tired. The only place I could find that did foam for them was Alpkit, so just ordered and fitted the foam from a Mujo. This is too big but cuts down easily with a breadknife. Original POD foam is around 8cm, this is around 9. Woomf foam is cheaper but a bit too thick. Right faff getting the new foam in, but once fitted, magic. And less than half the price of a new mat.
